-Employed at is a variable that is not relevant to the questions that I have posed, and is therefore omitted, as it cannot contribute to the accuracy of my analysis.

-Although the question of whether or not the shooter was employed is relevant, the specifics of employment are not necessary to include.

-Policeman Killed, and Open Close Location were also removed as these were not relevant to my analysis.

-Present useful detail in analysis, but it is only useful after the data has been processed.

-As Latitude and Longitude already provides a specific location, Incident area is uneccessary.

-Summary variable proves to be overly specific and does not help with analysis

-Substantial amount of values in the column ("Employed y/n)"), are missing.

-Including this column in the dataset would make for inaccurate results in my plots, therefore I removed this column.

-In the original dataset, the race column has 17 different races, some that are overlapped. I combined these 4 variations into one; "White" to make analysis easier, and did the same for other race categories.

-I ended up with just 6 race categories: White, Black, Asian, Latino, Native American or Alaska Native, and Unclear/Unknown.

-The same process was used for gender, to end up with 3 variations; Male, Female, and Unknown/Unclear

-The same process is repeated for Mental Illness, to end up with three variables: Yes, No, and Unknown/Unclear

-I found that the main causes of shootings in the US, were due to psychosis, terrorism motives, and anger and frustration.

-Other problems such as unemployment, revenge and racism, are also quite common.

-Although robberies would seem like it should be a higher number due to the number of robberies we hear about, the number of shootings that occur at robberies are quite low.

-Have there been particular time periods where there are more, does there seem to be a trend?

-Interestingly, we see that 2016 is the year with the most shootings, closely followed by 2015, which are both significantly far ahead, than all other years, from 1998.

-According to this plot, shootings have significantly increased in the US, evident in the fact that recent years such as 2013,2014,2015, and 2016 show higher number of shootings than previous years.

-Over time, there doesnt seem to be a specific trend of whether or not shootings have increased or decreased over time.

-Most shootings are concentrated in coastal area

-Less shootings in the mid areas.

-Shootings that do occur in the mid areas, seem to claim more victims than shootings in coastal areas.

-Most of the shooters were unclear/unknown regarding mental health issues, this may be due to lack of investigation or mental health checks following attacks.

-More shooters had mental health issues than those who didnt.

-Gap between shooters with and without mental issues was not much

-An overwhelmingly large number of male shooters

-Very few female shooters, this is reflected in the media
